; T all whomvlt may concern a citizen of the UnitedStates;residing-at Steubenvilleinthe countyof Jefierson and- -'State.oif Ohio,1*?have invented Lcertain new andnse'tul Improvements in Gas-Burners,

' of which the following is agspecification.

Thiswinvention relates to improvements in gas. burners ofthat type primarily in tended-for use in fire places and open face stoves al'lCltl16llk6-Wl16Tlll the flames are class wherein more perfect combustion is secured by. admitting-air at the P011) ofcombustion through the center of the fiame and burner; producing an odorless fire.

Another featurei f tl fii ti resides in "the particular manner 0f forming the burner Wltll" tubes concentric with the burner 'outlets and whlchserve to admit the air as above described.

@In the drawings:

In detail:

The burner, as shown in Figs. 1 to 4; inclusive, comprises a body A consisting or end walls 1 and 2, bottom wall 3, and top wall 4 the latter having a series of burner bosses 5'spaced therealong and which are drilled or reamed to provide openings of the proper size as indicated at 6 and which communicate with the chamber B formed by the walls previously mentioned. The bottom wall 3 is apertured, as indicated at 7 such apertures alining with the openings in the bosses 5 and being of slightly smaller Specification ofLetters Patent. I Patent ed Nflv. 29, 1921.

of their smaller size, leave a ringopening' 6 previously mentioned andwhich forms the opening for the* escape of the gas i roin within the chamber B. 'The chamber B is supplied withigas mixedwith air through the medium otrisers 1O which areinte 'ral with the body B' and also with a body C forming a header 11 provided with a centrally located boss 12 having the opening 13 which-communicates with the passage 14 of an elbow 15 having ai' fiange 16 secured to :the boss12-by means of screws "or the like 17 A? gasket lSJnay be interposedbetween the boss 12:. and theflangevlG- toprovide a will the boss '12. The elbow 15is provided with a bell mouth 19 and is hung by a screw 20 entering a spot 21' cast integrally with the -header-11. "Parallel arms'22 are-drilled nozzle iniplace as will be hereinafter described.

The combined gas nozzleand valve as in-" dicated'in general-at D (see Fig. 7) corn-.

prises a body portion 24L having arms 25 provided with holes 26 through which screws pass for the purpose of mounting the gas nozzle D on the arms 22. A valve body 27 having a tapered bore receives the valve element 28 which is secured in place by'a washer and screw at the one end and carries a stop pin 29 engaging with the abut ments 30 to prevent the valve element 28 from turning so far around as to render its cutout portion 30 inefi'ective. A screw 31 extending into the squared recess 32 pro vides for fastening aturning key 33 in place. The gas line or supply 34 is connected with the threaded end while the upper end of the body 24 carries the tubular member 35 threaded at one end as at 36 on the exterior to receive a cap nut 37 and on the interior to receive the threaded head 38 of the needle valve 39, a knurled-thumbpiece 40 being provided for rendering adjustment easy. The forward end of the tubular member 35' is also threaded on the exterior to receive a battle flange 4.1 which is adjustable back and forth between the arms 22 to regulate the amount of air taken in throu "h the passage 14 and mixed with the gas. 11 the interior the forward end of the tubular member 35 is threaded to receive a nozzle tip 4-2 having 7 p size and receiving tubes 9 which, by reason Bei it known that I; GnonenE. SHARPIL' 1 lated through adjustment of the needlevalve a conical recess 43 receiving the conical en'd 1 4 of the needle valve 39'and having an outlet 45 whereby the amount of gas is reguby turning the knurled thumb-piece 40,.

In the modification of the burner as shown in Figs. 5 and 6 the construction is identical with that just described except for the fact that the body46 and the header 47 are cast separate and joined by flanges 48 and 49 connectedby bolts or other securing means 50,a suitable; gasket being interposed *between the flanges j V In'the operation of the burner the needle valve 89 is adjusted to feed the proper grades of gas.

I claim: v I

1. The combination in a gas burner, of a longitudinal head having alining burner openings in a horizontal plane, means for supplying a combustible mixture to the openings including spaced risers leading into the bottom of the head and associated with gas mixing means, and means for supplying an additional quantity of air at the interior of the zone of combustion ofeach'burner open- 1ng.

' 2. The combination in a gas burner, of a longitudinal head. having burner openings, auxiliary air supply means centrally of these openings, means for distributing a combustible mixture uniformly to such openings and including a user approx mate each end of the head, and gas mixing means associated with said distributing means.

3. In a gas burner, the combination of a hollow body having alinedopeningsextending longitudinally of its; upper and lower walls, the openings'in the'lower wall of the body being of less diameter than the openings in the upper wall thereof, open-ended air conducting tubes fitted snugly in the, openings in the lower wall of the'body and extending across the body and into'the openings in the upper wall thereof, gas-conducting risers communicating with the interior of the body; adjacent the ends thereof, a header connecting the lower ends of said risers, an elbow secured to the-said header and communicating therewith through the bottom of thesame, a tubulargas supplying body carried by the outer end of said elbow and discharging into the same,'regulating devices disposed within said gas-supplying tubular body, and a bafiie secured upon said body and adjustable longitudinally thereof toward and from the outer end of theielbow. In testimony whereof I aflix my signature.
